I still don't get something: it is written in the arrangement manual under 
"Traversal Methods for an Arrangement Halfedge" (paragraph 2):

"The source() and target() methods return handles to the halfedge source and 
target vertices respectively"

And the example there show usage of these methods. However, as mentioned, 
they do not exist. What am I missing here?

Amir.

No. You can get one from the other, as you probably know.

No
